I believe one of the bigger tracks on Maui is called Kaihaku (sp?) Mx? Correct me if im wrong...

The stock fork spring comes with way too much spring pre-load which can be fixed by installing a shorter aftermarket spring, removing material from the spring collar...etc. Once you have the correct front/rear spring rate, pre load, sag settings, fork height etc... if your still having significant harshness, lower oil level, and for an extreme measure try throwing a cross...

It looks like a Cosworth Intake cam. Someone correct me if I'm wrong
